Re: 4.0L head bolts

Found my head bolts. Went to a local jeep restorer, "The Jeep Doctor" and he let me sift thru his boxes of parts from pulled apart sixes. Seems some 4.2's did come with 1/2" head bolts that were shorter on the spark plug side. Manual says 1/2" bolts are to be torqued to 105 ft lbs. Just like a 4.0L. Put her back together last night and it's purrs like a kitten. Replaced the one noisy lifter and that eliminated the tapping noise I have been hearing for the last 3 years!

Can't believe that an 84 CJ used 3 different fasteners for the valve cover! AMC keeps me laughing!


84 CJ7, 258, HEI, M/C 2100 carb, 5 inch lift, RS9000's, 33x12.5 BFG M/T's, Lockright, full cage & belts, Xenon flares, AMC 20 1pc axles, GM dual diaphragm brake booster
